With Tray 8, I have officially passed the 30% mark of Invisalign treatment. I still can't figure out why my top teeth that I thought never would need treatment are the ones that have straightened out the most. The lower teeth which I thought weren't moving at all, have moved so much that at Thursday's cleaning, the dental hygienist was super excited to find new areas to scrap away at. The dentist was happy, so if they're happy then I'm good. The top tray seems to be smoother this week so I hope it's leveling off.
